Product Description

The MERSEN GSA Series is a time-delay cylindrical fuse, rated at 750 mA and 250 V AC, with a non-indicating design and dimensions of 1/4 in x 1 1/4 in. It is equivalent to the MDA and GSA fuse series, identified by manufacturer part number GSA3/4.

Frequently Asked Questions

What is the MERSEN GSA Series fuse used for?

The MERSEN GSA Series time-delay fuse (750 mA, 250 V AC) protects electrical circuits from overloads and short circuits in industrial control panels, motor starters, and lighting systems. Its time-delay characteristic allows harmless inrush currents without nuisance tripping, making it suitable for inductive loads.

What are the specifications of the MERSEN GSA3/4 fuse?

The MERSEN GSA3/4 is a 750 mA, 250 V AC time-delay cylindrical fuse with a non-indicating design. It measures 1/4 in x 1 1/4 in and is equivalent to the MDA and GSA series. The manufacturer part number is GSA3/4, and it is part of the MERSEN GSA Series.

Where to buy MERSEN GSA3/4 fuses worldwide?

How to select the correct MERSEN GSA Series fuse for an application?

To select the correct MERSEN GSA Series fuse, verify the circuit voltage (250 V AC max) and current rating (750 mA for GSA3/4). Ensure the time-delay characteristic matches your load's inrush profile. Confirm physical dimensions (1/4 in x 1 1/4 in) fit the holder. Consult MERSEN application notes for specific motor or transformer protection.
